There is an image of a girl swinging on the “A” of “Park” while the “-ing” are blotted out.  The swing provides a nice diagonal to point towards the think text.  Having the “-ing” blotted out, but still readable, is a good choice to show that anything as simple as a parking lot can be transformed into a playground park.  Plus, I just really enjoy this artist and his work.  Banksy is my design hero.

Your eye goes right towards the red, large “park,” but is brought down to the girl to expose the literal meaning of “park.”
